Download the free helper
The free helper is a set of instructions for Claude, an AI assistant. Once you add it, Claude keeps a careful written record of your research. It notes where each statement came from, keeps a guess separate from a checked fact, and never quietly turns one into the other.
It needs Claude on the web or desktop app, with “Code execution and file creation” turned on in Settings, then Capabilities. Add the helper on a laptop or desktop computer. Once added, it also works in the Claude app on a phone or tablet.
Your own papers and notes stay on your computer unless you upload them. Anything you give Claude, including the notes the helper writes there, goes to Anthropic under your account settings.
Before you continue
Turn off “Help Improve our AI models” in your Claude account’s Privacy settings before you use it. Our privacy guide shows you exactly where.
How to get started shows you how to add it to Claude.
